lgtm, thanks, I ran dart2analyzer tests on the package, but didn't think that it
needs to be run in strong mode.

Is there a way to do that in test.py and the bots or not yet?

Good question.  I don't know why this wasn't caught by the dart2analyzer tests. 
I'll investigate.

I looked into it and I don't see an easy fix.  I've filed
https://github.com/dart-lang/sdk/issues/28013 to track the issue.
